Your theory is quite illogical. Your premise is wrong - where did you get that estimate? -, but more importantly your fat cells aren't going to start dissolving if your blood has slightly higher oxygenation.
"You exhale the carbon dioxide and the water mixes into your circulation until it's lost as urine or sweat. If you lose 10 pounds of fat, precisely 8.4 pounds comes out through your lungs and the remaining 1.6 pounds turns into water. In other words, nearly all the weight we lose is exhaled."
I used to be fat too and the only thing that worked for me was calorie counting. I hope you find some way to achieve your goals one way or the other.
